sMPRovEMENT IN Srovss.

Specification forming part of Letters Patent No. 152,509.. dat( d June 30, 1874; application tiled August 4,1873.

To all whom 'it may concern:

Be it known that we, JOHN S. PERRY and ANDREW DrcKEv, of Albany, in the county of Albany and State of New York, have invented cert-ain novel Improvements in Stoves and Furnaces; and we do hereby declare that the following' is a full, clear, and exact description thereof, reference being had to the accompanying dra-wings, making part ot this speciiication, in which- Figure 1,Plate l, is a front elevation ot" the stove. Fig. 2, Plate l, is a top view ot' the base-section without the grated ring. Figs. 3 and 4, Plate l, are views ofthe gra-ted ring. Figs. 5 and 6, Plate l, are views ot' the grate or tire-bed shown in Fig. 2. Figs. 7 and 8, Pla-te l, are views of a sectional grate or tirebed represented applied to the stove in Fig. 9. Fig. 9, Plate 2, is a section taken vertically and centrally through the stove or furnace from front to rear. Figs. 10 and ll, Plate 2, show the construction ot' the grate or lire-bed represented in Fig. 9.

Similar letters of reference indicate corre sponding pa-rts in the several iigures.

Our object is to improve base-burnin g and surface-buruing stoves and furnaces by the v application of a grated ring at the base ot' the lire-pot, the grated portion of which ring is elevated and located opposite the illuminating asltpit door, so as to expose to view the light of the fire, and also support the fuel at the front of the fire-pot.

The following description of our improvements will enable others skilled in the art to understand the same.

In the accompanying drawings, A represents the base-section ot' the stove or furnace; C, the section which surrounds the ire-pot C', B, the illuminati11g-section above the tire-pot or lire-chamber, and D the cylindrical upper portion ofthe stove or furnace.

The stove represented by Figs. l and 9 is a surface-burner; but it may be converted into a base-burner by the introduction above the tire-pot or tire-chamber of a fuel-magazine in the usual well-known manner 5 or, it' desired, the heater may be converted into a cook-stove or furnace.

rlhe base-section A .contains an aslrpit, F, which is nearly surrounded by a horizontal flue-chamber, L, which flue communicates bchind with an ascending flue, G, and above with the lire-chamber. the chimney, and connnunicates with the tireehamber by means ot' a short pipe, g', in which a damper, g, is applied for the purpose 0f giving a direct draft from the fire-chamber into the iiue Gr when such draft is required. The openings q through the upper margin of the tire-pot C, allow the products of combustion to dive down all around the outside ot' the lirepot through the lines s s, and enter the iiuechalnber L through openings c when damper g in direct ue g is shut, as shown in Fig. 9. At the lower end of the tire-pot C is a ring,

N, which presents a grated elevation, N, at

its front, the grating or teeth ot' which are inclined inward, so as to form a bank for supporting the coals which impinge against it. By this grated elevation an increased illuminating area is obtained. The elevated grated portion N of the ring N rest-s upon an elevation, a2, which projects downwardly over thc front passage leading into the ash-pit, which elevation is perforated, and provided with a laterally-movable register, n, the handle al of which projects through a slot made through the front ofthe stove. By means of this register more or less air from the ash-pit F can be conducted, when the damper g is open, into the liuc-space s s surrounding the tire-pot, and thence through openings q into the fire-pot. rlhe passage leading into the front of the ashpit is provided with doors E, which extend above the level ot' the lower end of the lire-pot, so as to cover the arch u2. To these doors E we supply transparent windows or doors a a., which are hinged so that they can be opened and shut. A poke-hole, provided with a door, I), and two registers, b `b', are also applied to the ash pit doors E. The windows or doors a a are directly in front of the grated elevation N ot' the ring N; consequently the light of thev lire inside ot' thcgrates will be exposed to view through said doors or windows a a, and the condition ofthe tire at the base of the fire-pot can be seen at a glance without opening the ash-pit doors.

Figs. 2, 5, and 6 show a grate or ire-bed which presents a ilat face, and which is made up ot' three detachable rin frs, J J l J2. The i11- The tlne G leads to ner ring J is grated, and is supported at three points, t', i, and j, by means of the ring J. This section J can be tilted forward to discharge the contents of the fire-pot into the ash-pit. The ring-section J1 is supported by an annular rabbet in the outer ring J2, which allows this section Jl, with its grated section J, to be oscillated laterally. The outer ringseetion has its periphery scalloped, and the outer edge may be turned up more or less to prevent the escape of unburnt coals into the ash-pit, and it is supported by three lugs, two of which, fj", allow the entire grate or tire-bed to be tilted or dumped forward.

y rlhe grate or fire-bed k (represented in Figs. 7, 8, 9, l0, and 1l) is dished, and is supported by a central pivot upon a rocking bar, k2, the ends of which have their bearings in lugs f f. rlhis grate or tire-bed can be oscillated horizontally, orit can be tilted or dumped forward Asuficient to allow the contents of the irc-pot to be discharged. The grate or tire-bed is of greater diameter than the inside diameter' of the fire-pot or nre-chamber at its lower end, as shown in Fig. 9, and this is arranged a short distance below the tire-pot or re-chainber, so as to leave a space, 3, for the expansion of the coals upon the grate or fire-bed, and for the introduction of a poker, by means of which elinkers and cinders can be expelled without dumping the grate or fire-bed, or disturbing the lire. In order to employ a grate or lire-bed of said larger diameter, I make it of two or more sections, k k1, and connect these sections together by means of tongues h and slotted lugs h. The tongues are formed on the bottom of one section, and the slotted lugs on the bottom ofthe other sections, and when the two sections are together the loops and lugs interlock. It", for any reason, it is desired to remove this grate or fire-bed, the two sections are detached, when either one of them will be smaller than the ash-pit, and can be removed through it.

By thus constructing a grate or re-bed it can be made of a diameter considerably larger than the bottom of the re-pot or .fir-echamber, or the width of the ash-pit door, and thus can be conveniently passed through the latter.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

rlhe separate ring N, arranged at the`- base of the tire-pot, and constructed with a grated elevation, N', opposite the transparent windows or doors a, substantially as described.
